# mail2s9y.php, 0.7
|
|
# -----------------
|
|
#
|
|
# Seperate PHP-Script to allow email blogging.
|
|
# REQUIRES: PHP CLI-binary, Linux/Cygwin(?), local Mail installation.
|
|
#
|
|
# Contributed by Sebastian Nohn <sebastian@nohn.net>, Gijs van Tulder <gvtulder@gmx.net>
|
|
# Implemented by the Garvin Hicking <me@supergarv.de> of the s9y group (www.s9y.org)
|
|
#
|
|
#
|
|
# Changes:
|
|
# --------
|
|
#
|
|
# 0.7 (2005-05-30): Needs Serendipity >= 0.7 now to properly import categories
|
|
# 0.6 (2004-04-13): Update with patches from amonthera (related to lowercasing attributes)
|
|
# 0.5 (2004-02-20): An security update by Alex Copeland, who pointed out that images could be uploaded without authentication.
|
|
# 0.4 (2004-01-19): Another update from Bjoern Schotte, who added interactivity to s9y. It will now mail back to ask for a category for the item.
|
|
# 0.3 (2004-01-13):
|
|
# Automatic URL replacement (translates http://... and other common protocols into hyperlinks). Thanks to Bjoern Schotte for the patch!
|
|
# Made Login modes working for s9y 0.5-CVS again
|
|
# 0.2 (2003-12-02): Beautified code
|
|
# 0.1 (2003-12-01): 3 different authentication methods are now available (security issues)
|
|
# Resets any cookie/session variables to block webrequests to this page
|
|
#
|
|
# To get this to work, do the following:
|
|
# --------------------------------------
|
|
#
|
|
# 1. Possibly adjust the first line of this script to point to your PHP CLI-binary. Put the package
|
|
# PEAR-Package Mail_Mime (http://pear.php.net/get/Mail_Mime) into your s9y/bundled-libs folder, so
|
|
# that you have an existing s9y/bundled-libs/Mail/mimeDecode.php file.
|
|
#
|
|
# 2. Make your local MTA recognize an E-Mail adress to be responsible for s9y. In most setups,
|
|
# just add the following line to your "/etc/aliases" file:
|
|
#
|
|
# s9y: "|/path/to/mail2s9y.php [username] [password]"
|
|
#
|
|
# The name 's9y' refers to the email account you chose to use for your local mail server.
|
|
# Of course, change the path to something valid.
|
|
#
|
|
# If you use the 'cmdline' authentication method (configuration see below) you have to provide
|
|
# the [username] and [password] credentials to your s9y-installation. If
|
|
# password-security is important to you, use a .procmail forwarding rule and set appropriate
|
|
# file permissions to your .procmail file (0600). However, the preferred authentication method
|
|
# is 'mailbody' and should be used to disallow anybody to mail a blog entry to your special
|
|
# email account, if ever exposed to the public.
|
|
#
|
|
# If you don't know how to setup an account or adjust the line above to a .procmail rule,
|
|
# you most probably don't want to use this script at all.
|
|
#
|
|
# 3. Adjust the variable $params['s9ypath'] below to point to your s9y installation.
|
|
#
|
|
# 4. MAKE SURE, that your mail-account user is in the same group as the owner of the file
|
|
# 'serendipity_config_local.inc.php'! Otherwise, your configuration can't be read.
|
|
# Usually, the file belongs to the webserver, so if you don't want to stick the user into
|
|
# the same group, you have to change the ownership of the file to your target user. Bear
|
|
# in mind, that the original permission ('ug+rwx') are updated any time you make changes to
|
|
# your s9y-setup.
|
|
#
|
|
# 5. Write an E-Mail to your chose local address. The subject will be the title for your entry,
|
|
# the body your text and possible attachments will be uploaded to your s9y directory structure.
|
|
#
|
|
#
|
|
# Also make sure that...
|
|
# ----------------------
|
|
#
|
|
# * Preferably your E-Mail blog-message should contain no unwanted
|
|
# linebreaks after the usual 70 char limit. If your E-Mail client does
|
|
# that to you, try to configure it not to; otherwise this may result
|
|
# in an ugly HTML display in your blog, and/or broken HTML tags you could
|
|
# have posted
|
|
#
|
|
# * If you use automatic URL rewriting (which transforms http://, ftp://,
|
|
# ...) links into valid HTML, please take care that this url is without
|
|
# any special characters (brackets, punctuation characters, ...), or else
|
|
# you may get those characters included in the auto-guessed URL.
|
|
#
|
|
# * If you use Sendmail versions above 8.12, it requires you to create
|
|
# a symbolic link in /etc/smrsh or /etc/mail/smrsh pointing to the
|
|
# mail2s9y.php script to allow sendmail permissions to execute the script
|
|
# from an /etc/mail/aliases entry (thanks to Thomas Brown for pointing
|
|
# this out!)
|
|
#
|
|
# * Feedback is appreciated! If anything doesn't work, please post your
|
|
# problems to either the s9y-support forums/mailinglists or mail the
|
|
# author personally.
